OlL-VAPOR-BURNING .SOLDl ERlNG-FURNACE.

SPECIFICATION forming part of Letters Patent No. 303,316, dated August12, 1884.

Application filed November 3, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM G. NORTH, of Cleveland, in the county ofGuyahoga and State of Ohio, have invented certain new and usefulImprovements in Oil-Vapor-Burning Soldering'Furnaces, of which thefollowing is a specification.

These improvements relate to the peculiar construction and arrangementof the burner and the adjacent parts of the furnace, as hereinafterdescribed and claimed.

In the drawings, Figure l is a perspective view of a soldering-furnaceembodying my improvements. Fig. 2 is a vertical section, and Fig. 3 is across-section, of same. Fig. 4 is a top or plan view of table offurnace. Fig. 5 is an under side view of part of the burner, showingprotector.

Ais the table of a solderingiron-heating furnace supported by legs atthe four corners. Heretofore these tables have had an open centersurrounding the burner, which caused a considerable waste of heat, andheated the lower parts of the burner and valvestem, and the flames wereunsteady from interference by currents of air from outside. Myimprovements entirely overcome these defects and produce an intenselyhot blue flame, uniform and rapid in effect.

The burner B consists of vapor-generator I), attached to the supply-pipeP at rear of table, and provided with vapor-pipe q, having needle-valveo and cup u. The pipe P at the angle is secured to the table-extensionby a tenon on the elbow Z, fitted into a mortise in the extension andheld by a set-screw. A plate, 0, is fitted to fill the opening in thetable, and lies just beneath said generator. It has a slot, 0, openingfrom rear side, so that it may be slipped into place from the front, andhas an ear, 6, through which a screw is placed to hold it in place. Saidslot 0 is enlarged at the center, and forms an opening,

through which the vapor passes to strike the under side of thegenerator, and here is where the vapor is burned, the flames from whichare spread and issue at each side of said generator, between it and theplate 0. The soldering coppers or irons lie on each side of saidgenerator and are heated by said flames. The plate 0 is supported at therear side by an arm, m, on the table, and this partly closes theslot.The burner is covered by a hinged hood, H.

To protect the generator from the intense heat, which in a short timerenders the metal of which it is composed very brittle and liable tobreak, I provide a protecting-plate of iron, I, to the under side,secured by means of a screw or rivet.

A shield, s, is made on the vapor-pipe q, standing between the orificeand the pipe, for the purpose of directing the flame which strikesagainst said pipe down its side, and prevents its interference with thestream of vapor issuing from the orifice.

The back wall of the hood has an opening, h, through which the pipe 1?passes, which is somewhat larger than the pipe. This allows flame toissue and extend along said pipe for heating it and assist in thegeneration of Va por. With this construction I am able to produce aperfectly blue flame from coal-oil, with an intense heat well adaptedfor the purpose required. I

Having described my invention, I claim- 1. In a vapor-burningsoldering-furnace, the removable plate 0, provided with central opening,a, in combination with table A and burner B, substantially as shown anddescribed.

2. The combination of the shield 8, the vapor-pipe q, and the generatorb, the said shield being parallel to the pipe, as and for the purposespecified.

WILLIAM 0. NORTH.
